The DA 18-135mm is certainly not a boring lens. It is in fact, a very capable lens of producing very fine images. The thread "DA 18-135mm WR- show us what it can do.." can be visited in the lens section of the forum. I recommend just start with the latest entry and work backward.
Of course one can consider the extra-fine qualities of shooting with Limited primes, but this by no means detracts what this fine zoom lens is capable of, and I say this owning and using both. Speaking of limiteds, we must remember the OP has stated being on a very limited budget. It must also be remembered, the DA 18-135mm WR lens is a very well-built lens, especially considering the price point to be had when bought together with the K-70, and the fact that shopping for a zoom lens featuring Weather Resistant construction in other brands such as Canon or Nikon would mean shopping in the $1,000+ price range. Shopping for a body having such an advantage would be looking at another $1,000+. All current Pentax bodies are built having this feature. From this perspective, spending more and getting the ultra-fine compact model, the KP with the DA 18-135mm WR would still be an amazing bargain by comparison.
